one is 25-5
second 19-3
Hello there!
Thank you for reaching out to us. We can help supply this balance but it will have to be a custom order due to its configuration. The pulley wheel is built into the bottom fitting itself and this balance features an extended cord travel as well as a metal channel length ending in 5/8" which is what makes it custom. I just need a bit more information so I can get this moving for you.
Can you show us a photo of the metal clip attached at the end of the pulley cord? Would it also be possible to see a photo of the bottom fitting from a side angle? And how many balances are you looking to order?
We're almost there! Can you show us a photo of the bottom fitting from a side angle? You can use the image below as a reference for what I mean. We also still need to see the metal clip attached at the end of the pulley cord. You may want to check an undamaged balance for an intact clip.

Great, thank you! What I will do now is email you a purchase link and price quote for (2) balances with the 19-3 stamp and (2) with the 25-5 stamp. You can use this to place an order on our website at your convenience.
Let us know if you have any questions!
